Savory Seaweed Seasoning

My homemade seaweed seasoning recipe with just a few ingredients. Adds a nice savory kick to all kinds of dishes including everything from steak to popcorn!

Savory Seaweed Seasoning

Sometimes the most important part of a recipe can be the last 1%. If you’ve ever tasted a dish and thought: It’s just missing something, then you know what I mean. A little sprinkle of salt or dash of something can make all the difference.

I’ve been casually working on this seasoning mix for a few weeks now and while it looks simple enough (and it is), it also brings some intense flavor to whatever you put it on. It’s packed with savory umami flavors and just enough spice and salt to make dishes really pop.

It’s dumb easy to make, but once you give it a shot, you’ll find yourself sprinkling it on everything from popcorn to that grilled steak.

It’s like magic flavor dust.

Seaweed Seasoning Recipe

Just a moment please.

Show Directions

1) Crunch up seaweed sheets so they fit in the spice grinder. Pulse a few times until in small pieces.

2) Add wasabi peas and salt to the grinder and pulse until it’s in a coarse seasoning mix.

3) Use a fork to pick out any large bits of unground wasabi pea.

Store seasoning mix in an airtight container. Use liberally as a finishing seasoning on foods that need a savory/salty kick.

Savory Seaweed Seasoning

Most people are probably used to seeing seaweed only in sushi form, but you can find these sheets now at almost any grocery store. Make sure you buy the roasted sheets. They should be thin and somewhat crispy.

Also, don’t use the seaweed chips that are available these days. Those are good, but also have oil and stuff on them which can make the seasoning mix clump together.

If you just ground up seaweed and tasted it (I did), it is intensely savory. It’s like sticking a dried mushroom in your mouth. It’s too much of one thing.

But we can add few things to it to make it more rounded.

First, wasabi peas! These might sound weird but they totally work in this. For starters, they add a little spice, but possibly more importantly, they give the seasoning mix some bulk because the peas themselves are fairly bulky and flavorless.

This works to spread out the savory flavor a bit.

Grinding the Seasoning

I tried to grind this one time in a mortar and pestle and it’s a lot of work to get everything into a fine texture. A cheap little spice grinder makes quick work of it though.

You’ll have to crumble the seaweed sheets with your hands and then just shove them in the grinder.

Pulse the sheets a bit to break them up and then add the peas and salt. As these start to grind, the will help grind the seaweed even finer because of the extra texture.

When the mix is mostly ground, transfer it to a storage container. I recommend using a fork to strain out any large pieces of wasabi peas that didn’t pulse completely so you are left with a nice, fine spice mix.

Savory Seaweed Seasoning Uses

You can and should sprinkle this stuff on anything that needs a savory kick, but don’t cook the seasoning. It loses some of its punch if you cook it, so use it as a finishing spice.

A few use options:

– Popcorn! Buttered popcorn!
– Grilled steak sliced thin.
– Any sort of Asian noodle bowl or soup.
– Any tofu dish.
– Kick up bland salads.
– Eat it with a spoon (okay maybe not).

Seaweed Mask Recipe

Remember when “me time” was a late-night movie marathon, sleeping in the next day and – most importantly – sitting in silence for as long as you want to? Yeah, me too. Though I wouldn’t trade these days with my littles for anything, I do love to sneak in some good old-fashioned pampering as often as I can. (And hey, it doesn’t hurt if it makes me feel just a little more glamorous while I rock my top knot for the third day in a row.)

Sometimes it’s one of these methods for rebooting my body’s stress response, and sometimes it’s a luxurious at-home facial. This seaweed mask recipe is similar to the $175 signature service offered at my local spa, but I can get one every week for about $0.25 – $0.35, depending on what I use as a base for the mask.

Seaweed = Skin Superfood

Now, it’s no secret that I love to use sea-derived ingredients in my recipes – this sea mud soap, for example. They’re deeply nourishing and very affordable if you make your own. If you’ve never incorporated seaweed into your skincare routine, you’re in for a treat. It nourishes skin with vitamins and minerals (including over 70 trace minerals) that support collagen production, plus polysaccharides and antioxidants.

That’s the short version, of course. For geeky science details, check out the section below. If you’re in a rush and just want the recipe, skip to the bottom.

Benefits of Seaweed for Skin

L-Fucose for Collagen Support

In this study, researchers found that a 1% extract of Fucus vesiculosus – a type of brown algae/seaweed – supported collagen production when applied to skin. This is huge, because not all nutrients are well absorbed by the skin. Collagen is the perfect example of this – it’s molecules are too large to penetrate the skin, so it just sits on the surface until it is rinsed away. (source)

Some researchers believe the benefits of Fucus vesiculosus are due in part to substantial amounts of L-fucose, a polysaccharide that is also found in other types of brown algae/seaweed. (source) The kelp I use in this recipe – Ascophyllum nodosum – is confirmed to also contain a significant amount of L-fucose. (source)

Clinical research has also shown that a cream containing 1% chlorella – the other algae used in this recipe – had a beneficial effect on firmness and tone. (source) As you’ll notice in the recipe below, I sometimes rotate kelp with chlorella.

Vitamins & Minerals

Seaweed offers “one of the broadest ranges of minerals of any food,” including macro-minerals like potassium, magnesium, phosphorous, calcium and copper plus over 70 trace minerals including selenium, iron, zinc, manganese and molybdenum. (source 1, source 2)

Minerals such as copper, zinc, magnesium, phosphorous and manganese are essential to the synthesis of collagen, and “Unlike many organs, skin nutrition may be enhanced directly through topical applications. Topical application of micronutrients can complement dietary consumption, leading to a stronger, healthier protective barrier for the body.” (source)

Not all forms of minerals are absorbed well by the skin – one example is non-nanoparticle zinc oxide, which is used to make homemade sunscreen due to it’s ability to coat the surface of the skin. However, there are forms that can be absorbed, and many aestheticians believe that those found in seaweed, unrefined salt and dead sea salt come with naturally occurring co-factors that optimize absorption.
For example, kelp contains carotenes (a precursor to vitamin A), vitamins B-1 (thiamin), B-2 (riboflavin), B-3 (niacin), B-9 (folate), C, E and K1- all of which support skin health. (source 1, source 2) In many (if not most) cases, these vitamins are thought to work synergistically with minerals to facilitate absorption – for example, vitamin C increases the body’s absorption of iron. (source)
Speaking of co-factors, seaweed also contains carotenes (a precursor to vitamin A), vitamins B-1(thiamin), B-2 (riboflavin), B-3 (niacin), B-9 (folate), C, E and K1- all of which support skin health. (source 1, source 2) As I mentioned earlier, they’re thought to work synergistically with many of the minerals present.

Vitamins also often have an antioxidant effect – several water and alcohol extracts of seaweed have demonstrated antioxidant properties, including an extract made from the kelp used in this recipe (Ascophyllum nodosum). (source 1, source 2)

Should I blend the seaweed with water or oil?

Some of the nutrients found in seaweed are fat soluble, meaning that they need fat of some kind to be present in order to be absorbed. However, based on the research I’ve done many of the minerals in seaweed are probably better absorbed with a water base. For that reason, I tend to alternate which type of base I use between aloe vera gel (which is water-based), yogurt (which contains both water and fat), and oil.

Video: Seaweed Mask Recipe

A few weeks ago I stopped by Thrive Market and made this mask in their studio using aloe vera gel, kelp granules and spirulina – thought I would share it with you so you can see how easy it is!

Oh, and there’s one last thing you need to know . . .

Like my beloved valerian root tincture that supports deep sleep, this seaweed powder has a not-so-appealing scent. It’s not very strong, but you may want to incorporate an essential oil to improve the fragrance while also imparting additional skin benefits.

Seaweed Mask Recipe (With Kelp and Chlorella)


  • 1/2 teaspoon kelp powder (I use this kind and it’s amazing, but it’s a little coarse. I usually sift mine with a flour sifter and use the coarse stuff to make body scrub, but when I made it with kelp granules at Thrive Market I like of liked the texture it added, too. Just use what you have. ?
  • 1/2 teaspoon chlorella (Here’s where to find it. spirulina can also be used but be aware that it can impart a temporary light yellow tint to skin)
  • 1 tablespoon full fat yogurt – OR – 1 tablespoon aloe vera gel (fresh if possible to avoid weird thickeners and preservatives) – OR -2 teaspoons skin nourishing oil (coconut oil is an option, and there are many more listed here)
  • 1 drop skin nourishing essential oil, optional (I love this anti-aging blend – it’s affordable, it smells like honeysuckle and it contains all the best essential oils and absolutes for skincare – neroli, rose, jasmine, geranium, sandalwood, Roman chamomile, German chamomile, sweet fennel, carrot seed, lemon, lavender and frankincense)


If using an essential oil, add it to the kelp/chlorella powder and stir until it is thoroughly blended in. Add in yogurt/aloe vera gel/oil and blend again. If needed, add more liquid until the mixture creates a smooth, spreadable consistency. (If using yogurt or aloe vera, I typically add water. If using oil, I add more oil.)

Scoop out the seaweed mask with a spoon, then use your fingertips to apply it to your face and neck (if desired). I use a circular, rubbing motion to gently exfoliate as I apply. Allow it to sit for 15-30 minutes, then rinse. Follow with moisturizer.

Shelf Life

For the yogurt base, about one week if stored in the fridge. For fresh aloe, about two days in the fridge. An oil-based mask will last longer – at least several weeks in the fridge.
